WATER-CLOSET.

SPECIFICATION'forming part of Letters Patent No. 349,293, dated September 14, 1886.

Application filed January 9, 1886. SeriulNo. 188,093. (No model.)

.To all whom it may concern.-

Be it known that I, WILLIAM H. UMPLEBY, a citizen of the United States, residing in the city of Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful Improvementin Water-Glosets; and I declare. the following to be afull, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters and figures marked thereon, which form a part of this specification.

In ordinary washout water-closets, as there is no valve or similar device separating the vertical discharge-pipe from the basin or bowl,

washout-closet.

whatever foul gases and odors are given off from the matter remaining in the bottom of the disch argepipe pass immediately into the bowl, and thence escape into the room. This is such a serious defect as to more than counterbalance the other advantages claimed for the To remedy this an ordinary ventilating-pipe was sometimesconnected with the dischargepipe near its upper end; but here again the force of the flushing-water, as it sweeps through the bowl, is such that the paper and other solid matter swept out of the bowl is thrown up at the mouth of the ventilatingpip e, and that pipe, soon becoming clogged or closed at its month, not only affords no outlet for the foul gases arising from the t lischarge-pipe, but

itself supplies a lodgment for the solid matter thrown out of the bowl, and thus increases rather than decreases the foul gases discharged into the room.

the means of ventilating a washout-closet, by which the above-mentioned defects are reme died; and it consists in the improved form of closet hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top or plan view of my invention. Fig. 2 is a vertical. section of the same closet on the broken line 2 2 of Fig. 1. Fig. 3 is a vertical section through the ventilating pipes and the dis chargepipe.

Similar letters refer to drawings.

I am aware that washout water-closets have similar parts in the been made before having tubular rims with perforations and a central supply-pipe, and I therefore do not claim these features alone, but only in combination with my improved system of ventilation, in which combination alone all the above features are united in one complete and perfectly-operating closet.

A is the bowl of the closet. It is made concave with sloping sides, and is'square in general form, as in Fig. 1; but it may be made oval or of any other suitable form.

bis the tubular rim. The passage or channel 0 in the rim is made of any convenient size. The water is introduced into the rim through the supply-pipe, which is preferablyconnected with the rim at its central back portion; but thesupplypipe may be connected with the rim at any point desired. The rim portion projects in a little over the bowl, and in the under surface of this proj ecting part is a series of holes extending around the three sides of the bowl, preferably excluding the side over the discharge-pipe. These holes slope toward the discharge pipe, so that the water will be discharged through them in the direction of the discharge-pipe, and will tend, therefore, to wash the contents of the bowl in that direction. On the side of the bowl opposite the discharge-pipe there is a long slit or opening, (2, on the under side of the rim, as if several of the holes were joined or run into each other.

The effect of this is, that a larger body of water is discharged from this point, and is 7 dashed down and across the entire width of My invention relates to an improvement in V the bowl, so as to eompletel y remove the contents of the bowl. An additional force or impetus is given to this body of water, because the two streams of water that pass around the opposite sides of the tubular rim, meet immediately above the slot, and each stream serves to turn the other one directly down through the opening or slot with an increased force.

When the bowl is made square in general form, the sides of the bowl are so curved upward and outward as to form an edge at each corner on the outside of the bowl, and to make the upper surface of the rim square in form.

(See Fig. 1.) The inner portion ol'this uppor surt'aoe of the rim is a little dopressot'l. (See Fig. 2.)

cis tho dam at the back of the bottom of the bowl. It is made almost as wide as the bowl, and has a straight or nearly straight edge, so that the sides of the dam are not higher than. the middle point, except at; the extreme ends of the dam, whore it eurvos up into the sides of the bowl. The object of this is to onablo the contents of the bowl to be swept over the dam at any point with equal ease, and thus to make alargor space for the discharge.

In Fig. 2, as the sectional. line of plane 2 2 passes through the dam close to its end, the dam is shown in that figure as much higher than it is during the greater part of its length, and as approaching nearer to tho lip than it does at its central and surrounding portions. Immodiatolyback ot' the dam. the discharge pipe g. The mouth of this discharge-pipe is as long as the dam, and is also quite wide across from the dam to its back-wall. Below the pipe is contracted in. both directions. The discharge-pipe is bent or curved at tho top, so as to moot tho back wall of the bowl. In the drawings tho routilatiug-pipos aro connootwl with this uppor ouryod portion of tho discharge-pipe.

h. hare my two vont ilating-pipos. which open into the upper end of tho discharge-pipo. Those ventilating pipes are curved, as shown in Figs. il. 2, and 3, so that their mouths open into tho discharge-pipe in a direction away from tho bowl ot' tho olosot. Tho otfoot of this is, that when tho llushing-wator dashos the contents of tho bowl against tho baokuall ol' tho disohargopipo, tho mouth of each youtilatiug-pipo being turned away from tho bowl, as aboyoexplained, thomattordischarged l'rom tho bowl cannot be thrown directly up into tho veutilat ing-pipo, and thus thovontilating-pipo is prevented t'rom boiugstoppod or choked up, as happens with tho ordinary l'orm ot ventilating-pipe attached to tho discharge-pipo. Tho osoapo for tho bad gases gonoratod in tho bowl and disohargo-pipo is in this way always kept open, and such gases are thus u'o\'entod from being discharged into tho room. Tho upperpart of tho vontilating-pipos may be heatod in any ordinary way, so as to oauso a constant draft up and through thopipo. Iprotorto use two yentilatingpipos, as shown, though ono may be found sut'ticient.

In the old form of washout closets the contents of tho bowl are dashed against tho back. wall ot tho discharge-pipe, especially at; its middle portion, with such force that a part of such contents is thrown upward and backward against tho curved top of tho discharge-pipe, and, following tho curve ottho top, is thrown back again into tho bowl of tho closet. My invention avoids this ditiieulty the lip i, which projects down from the back wall of tho bowl, and thus cuts oil a small portion of the upper part ot the largo mouth by means of of the discharge-pipe from the bowl of the closet, and intercepts tho water and other contents thrown back. from tho back wall. of tho discharge-pipe, and thus prevents them from being thrown back into tho bowl. Thislip also serves to protect the mouth of the ventilating pipe or pipes.

In Fig. 2 the lines jjj indicate tho rolativo heights of tho exact; middle points of tho lip and the top of tho discharge-pipo. Tho discharge-pipe is curved around and up under tho bowl, as shown in Fig. 2, thus making'a trap integral with the rest of tho closet. A ventilating-1)ipo, 7:, passes off from the upper part of this trap. (See Fig. 2.)

Tho two yontilating-piposmaybo ('ouuoctod behind tho closet.
